Combustible compositions which contain as a flavorant additive substituted heterocyclic compound corresponding to the formula:
wherein X is selected from pyrazine and pyridine radicals corresponding to the chemical structures:
wherein R is a substituent selected from hydrogen and methyl, R1 is a substituent selected from hydrogen and alkyl groups having 1 to 10 carbon atoms, R2 is a substituent selected from aliphatic, alicyclic and aromatic groups having 1 to 12 carbon atoms, any heteroatom or atoms present in the R2 group being oxygen or nitrogen, with the proviso that the radical
may be an alicyclic structure.
In one of its embodiments this invention provides tobacco compositions which contain up to 2% by weight of a substituted-pyrazine flavorant additive such as 2,3-dihydroxy-2,3- dimethyl-1,4-bis (3,5,6-trimethyl-2-pyrazinyl)butane:
可燃组合物,其中含有与式相应的取代杂环化合物作为调味添加剂:
其中 X 选自与化学结构相对应的吡嗪基和吡啶基:
其中 R 是选自氢和甲基的取代基,R1 是选自氢和具有 1 至 10 个碳原子的烷基的取代基,R2 是选自具有 1 至 12 个碳原子的脂肪族、脂环族和芳香族基团的取代基,R2 基团中的任何杂原子为氧或氮,但该基团
可以是脂环结构。
在其中一个实施方案中,本发明提供的烟草组合物含有高达 2%(按重量计)的取代吡嗪香料添加剂,如 2,3-二羟基-2,3-二甲基-1,4-双(3,5,6-三甲基-2-吡嗪基)丁烷:
